Heh, I did the same, but I was stopped by our legalese disclaimer.

That would need to be adjusted first.

I do believe that certain derivations from the original sources can be legally clear, but need to ponder on this more.

Got you. I rephrased the description, removing some triggers. I found out that constants, formulas, and other figures aren't under copyright.
